Product description
LARA-R2 series modules support multi-band LTE-FDD with
six regional variants. Each variant is designed for specific re-
gional market requirements to allow development of cost-ef-
ficient yet feature-rich products. The variants with 2G or 3G
fallback provide connectivity in cases where LTE coverage is
not yet available. This allows seamless operation during tech-
nology transition.
With many interface options and an integrated IP stack, the
modules are designed to support a wide range of data-and-voice-
centric applications. The unique combination of performance,
security and flexibility make them ideal for medium speed M2M
applications, such as smart energy gateways, remote access
video cameras, digital signage, telehealth and telematics.
LARA-R2 modules support Voice over LTE (VoLTE) or CSFB
voice service for applications such as security and surveil-
lance systems.
Thanks to u-blox's CellLocate® technology, LARA-R2 offers
cost-effective location estimation based on information from
surrounding cellular base stations. A positioning solution with
CellLocate and a u-blox GNSS module provides redundancy
and accuracy that can be beneficial for numerous applications.
The temperature range of –40 °C to +85 °C guarantees op-
eration in harsh environments and in very compact designs.
The ultra-compact LGA package enables straightforward
automated manufacturing. The LARA form factor follows
the u-blox nested design principle in order to maintain design
compatibility between modules supporting different cellular
technologies. It is compatible with the SARA, LISA and TOBY
module families. This allow customers to easily upgrade their
products or develop new variants using the same footprint,
thus maximizing investments, simplifying logistics, and en-
abling a very short time-to-market.
LARA-R2 modules are manufactured in ISO/TS 16949 cer-
tified sites, with the highest production standards and the
highest quality and reliability. Each module is fully tested and
inspected during production. Modules are qualified according
to ISO 16750 – for systems installed in vehicles.
USB drivers and RIL software for Android are free of charge.
